I thin you're seeing too much in it. I didn't think he was laying the boot in.
His past comments has shown he would fancy himself to be a conduit for NBL team participating in a regional basketball super league of sorts.
He is approaching 70, the demands of coaching will be getting beyond him soon, if not already. I'm sure he wants some sort of short-season GM roll, and probably feels a role where he guides, and remunerated for, NBL teams in such a league is perfect for him.
The TLDR version
"Australia is saturated with sport and it's a hard task for the NBL to extract more revenue. Try heading into a league where (The Asian population) loves basketball and are in a position to spend. This is where the NBL should look to get more money from.
The top teams here spend big, and get top quality imports. Cam Oliver is one example, the guard from my team Myles Powell (imagine pumping tyres !!) is a gun, and equal to any top tier import in the NBL."
To be frank, if NBL teams could participate in such a com, where they could find themselves say $1.5 million each in a grant, it would boost the league so much.
I mean, if Mitch McCarron is the 14th highest paid player in the league on $300-400k, and Josh Adams the 3rd highest on $500-600k ... no one is really making hay.
